I went through some kind of burnout as well last year (more related to personal stuff than work itself) and decided to take a long vacation. I didn't want to go back to the usual schedule and risk having the same issue again in a year or two, so I decided to work part time when I came back. So, now I work Monday to Wednesday and have Thursday to Sunday free. This means I only have three days per week to make an impact on the company (as opposed to the ones who work full time), so I find myself really focused. My productivity vs before has skyrocketed. What do I do on my extra days? Sometimes I go out, sometimes I just do nothing and relax, sometimes I do small side contracts or personal projects. I hope one of these takes off one day and allow me to recover the money I gave up when switching to part time. At least now I've got the energy to work on them.
